Question

network hardware

There is a problem with such a plan. There is a tenda n304 router that distributes Wi-Fi around the house, a twisted pair with mikrotik sxt lite5 is connected to the wan port. After rebooting the router (tend), the router does not receive settings via DHCP, it is constantly written in red (Connection) and as a result Wi-Fi without the Internet. What manipulations need to be done to fix the problem? they didn’t fly off, everything is ok with the Internet, this was confirmed by the provider, no one touched the mikrotik, that is, everything became after the restart of the tenda router)

Answer 1

Disable DHCP on the n304, write any unoccupied static address from the Mikrotik network on its LAN interface, plug the wire from the Mikrotik into the LAN. Enjoy.
